The article indroduced the system of ore mixing of sintering based on data mining. Appled the method of cluster to the saved history data of the sintering process to classfy the history data into three category. Every new sample should be put into the Corresponding cluster by the distance of Eucliden, at the meantime, find the nearest proportioning ore case, and the quality index of the new sample is same with the nearest case. The method is more useful and easy.
Aimed at the problem that video image is often affected by noises, the principle of median filtering and improved algorithm is analyzed. A new algorithm of noise elimination is presented, whose experiment on video processing hardware shows its reliability and advantage: image noise can be removed and image details can be preserved effectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
